SAFETY RAZOR.

Application filed May 19, 1923. Serial No. 540,096.

. My invention relates generally to razors, and more particularly to arazor of the safety type, the principal objects being to generallyimprove upon and simplify the construction of existing forms of safetyrazors; to provide a safety razor having a blade holding head or framethat is curved lengthwise in order that it may be conveniently used oncurved portions of the body, for 1a instance, the axilla; further toprovide ina safety razor a curved head or blade-holding body that willfirmly clamp and retain the flexible-blade inproper curved position; andfurther to provide a structure that may be functions.

With the foregoing, and other objects in view, my invention consists incertain novel 20 features of construction and arrangements of parts,which will be more fully hereinafter described, and illustrated in theaccompanying drawings, in Which,-

Fig. 1 is a perspective view of a safety razor of my improvedconstruction;

. Fig. 2 is a perspectiveview of the upper or top plate that forms apart of the head or blade holding frame;

Fig. 3 is a vertical section taken approximately on line 33 of Fig. 1.Fig. 4: is a plan view of the lower plate of the head or frame.

Fig. 5 is a plan view of oneof the blades that is used in my improvedsafety razor.

Fig. 6 is a perspective view of the head of a modified formof the razor.

Fig.7 is a jcross section taken on the line, 77 of Fig. 6.

Fig. 8 is a plan view of a blade that is used in the modified form ofthe razor.

Referring by; numerals to the accompanying drawings, and particularly tothe con-v struction illustrated in Figs. 1 to 5, inclusive, 10designates the top plateof the head or blade holding, frame, which plateis curved lengthwise and depending from the ends of said curved plateareshort lugs 11.

Depending from the underside of the central portion of plate 10 is athreaded stud or shank'12. The lower plate 13 of the head or frame iscurved lengthwise to conform to the curvature of the plate 10, saidplate 13 being slightly greater in length and width than said plate 10,and the front edge of said easily and cheaply produced, and which willbe very effective in performing its intended plate 13 is provided withcomblike teeth 14,

the upper surfaces of which are curved or bevelled toward their forwardends.

Formed inthe ends of the plate 13 are notches 15 that are adapt toreceive the lugs 11, and formed in the center of said last mentionedplate is an aperture 16 that is adaptodto receive'shank 12.

A suitable handle 17, preferably a short metal rod, having the greaterportion of its surfacemilled er knurled, isprovided in its upper endwith a threaded recess 18 that is adapted to receive the threaded shank12.

The blade 19 used with this form of my improved razor is formed of verythin sheet steel or like metal having sufficient flexibility so that itwill readily conform to the curvature of the plates 10 and 13, saidblade being provided along one of its sides with a cutting edge 20 andin its ends with notches 21 that are adapted to coincide with notches 15so as to receive lugs 11 when the parts of the razor are assembled foruse.

Formed in the center of the blade is an aperture 22 that is adapted toreceive the stud 12.

Inassembling the parts of the razor just described, a blade 19 ispositioned against the underside of top plate 10 with the stud 12projecting through aperture 22, and with the lugs 11 ocoupylng notches21. Lower plate 13 is now positloned against the underside of blade 19with stud 12 projecting through aperture 16 and with the lugs 11occupying notches 15. The recessed end of the handle 17 is now screwedonto shank 12, and in so doing plates 10 and 13 are drawn together tofirmly clamp the interposed blade. I

When the parts are thus assembled, lugs 11 occupy the respective pairsof notches 15 and 21, thereby firmly retaining the two plates and theblade in assembled relation,

and the razor is now ready for use.

The widths of the plates 10 and 13 and blade 19 are such that thecutting edge 20 of the blade projects slightly'beyond' the front edge ofplate 10 and overlies the intermediate portions of teeth 14.

- lin the modified construction illustrated in Figs. 6, 7 and 8 the topplate 23 is provided on its rear edge with two or more depending lugs 24that are arranged so as to occupy notches-25 that are formed in thelower plate 26 and likewise occupy corresponding notches 27 that areformed in the rear edge of a flexible blade 28. in this construction thetwo plates and the blade are equal in length and top plate 23 isslightly narrower in width than the interposed blade and the lowerplate.

A safety razor of my improved construction is comparatively simple, maybe easily and cheaply produced, is constructed so that the flexibleblade is firmly clamped in the head or frame when the parts of the razorare assembled for use and the blade holding head or frame is curvedlengthwise so that it may be conveniently used on curved portions of thebody.

Minor changes in the size, form and construction of the various parts ofmy safety razor may be made and substituted for those herein shown anddescribed without departing from the spirit of the invention, the scopeof which is set forth in the appended claim.

I claim as my invention:

In a safety razor, a backing plate curved lengthwise and having'parallelfront and rear edges, the front edge of said plate being notched toprovide a series of teeth, the

assess? central portion of the plate being provided with an aperture, aflexible blade adapted to overlie said backing plate and having; itscutting edge positioned above and slightly to the rear of the forwardends of the teeth on the backing plate, said blade havin an aperturethat is adapted to coincide with the aperture in said plate, a top plateadapted to overlie said blade with its front edge positioned slightly tothe rear of the cutting edge of the blade, a threaded shank projectingfrom the underside of said top plate through the coinciding apertures inthe blade and hacking plate, a handle having a threaded recess thatreceives said threaded shank, the rear edges of said back plate andflexible blade coinciding with each other and being provided withcoinciding notches, lugs depending from the rear edge of the top plate.which lugs are adapted to occupy the coinciding notches in said backingplate and blade, and the outer faces of which lugs lie flush with theouter coinciding edges of the back plate and flexible blade.

In testimony whereof I have signed my name to this specification.
